“We’re creating digital representations of patients that can be used to simulate treatments before they’re ever administered,” explains a Mantis Biotech representative in their recent TechCrunch feature. My first thought? We’ve officially entered the sci-fi timeline, and I’m here for it.
But let’s back up. What exactly is a “digital twin” in medicine, and why should you care?
The Data Desert Problem
Here’s the issue: modern medicine runs on data. Lots of it. Doctors need to know how treatments work across different body types, genetic profiles, and health conditions. But gathering that data is expensive, time-consuming, and sometimes impossible. You can’t exactly test experimental treatments on thousands of people just to see what happens.
This is especially brutal for rare diseases. When only a few thousand people worldwide have a condition, finding enough patients for clinical trials becomes a nightmare. The result? Treatments that could work never get developed because the data simply isn’t there.
Enter Mantis Biotech’s solution: create virtual versions of patients that doctors can experiment on instead.
Your Avatar, But Make It Medical
Think of a digital twin as your medical doppelgänger living inside a computer. It’s built from your actual health data—genetics, medical history, current conditions, even how your body typically responds to medications. But unlike you, this virtual version can be subjected to countless “what if” scenarios without any real-world risk.
What happens if we adjust your medication dosage? How would your body respond to a new treatment protocol? Would this surgical approach work better than that one? Your digital twin can help answer these questions before anyone touches the real you.
The technology addresses medicine’s data availability crisis by essentially manufacturing the data we need. Instead of waiting years to gather information from actual patients, researchers can run simulations on digital twins and get insights much faster.
Why This Matters Right Now
The timing couldn’t be better. AI is already making waves in healthcare—TechCrunch recently covered how it’s helping tackle labor shortages in rare disease treatment. Digital twins take this a step further by giving AI systems something concrete to work with: detailed, personalized patient models.
For rare diseases especially, this could be transformative. When you only have a handful of patients to study, creating digital twins of each one suddenly gives you a much larger dataset to work with. You can test theories, refine treatments, and identify patterns that would be impossible to spot with limited real-world cases.
And it’s not just about rare conditions. Even common diseases could benefit. Imagine if your doctor could test different treatment plans on your digital twin before deciding which one to actually prescribe. No more trial-and-error with your actual body.
The Elephant in the Server Room
Of course, this raises some obvious questions. Who owns your digital twin? Where is that data stored? What happens if it gets hacked?
These aren’t hypothetical concerns. Just recently, Crunchyroll confirmed a data breach after hackers gained unauthorized access to their systems. Now imagine that happening with your complete medical profile.
The security and privacy implications are massive. Your digital twin would contain incredibly sensitive information—potentially everything about your health, genetics, and medical history. That’s the kind of data that needs Fort Knox-level protection.
What Happens Next
Mantis Biotech is betting that the benefits outweigh the risks. And honestly? They might be right. The potential to accelerate medical research, personalize treatments, and make healthcare more effective is enormous.
We’re also seeing parallel developments across biotech. Companies like Nephrogen are combining AI with gene therapy to tackle kidney disease, showing up at TechCrunch Disrupt 2025 to demonstrate their approach. The entire field is moving toward more personalized, data-driven medicine.
Digital twins fit perfectly into this trend. They’re essentially the ultimate personalization tool—a medical model built specifically for you, responding exactly how you would respond.
The technology is still early, and there are legitimate concerns to address around privacy and security. But the core idea—creating virtual patients to solve real medical problems—is genuinely exciting. It’s the kind of application where AI and healthcare intersect in ways that could genuinely improve lives.
Your digital twin might not be ready to take your place at family dinners, but it could help your doctor make better decisions about your health. And in medicine, that’s worth paying attention to.
